Electronmicroscopy of Dental Calculus
Science, 1960Electron microscopy of ultrathin osmium-fixed sections of dental calculus, cut with a diamond knife without prior decalcification, revealed densely mineralized areas entrapping many degenerating microorganisms, within which were deposited similarly electron-dense crystals.

Radiographic Detection of Dental Calculus
Journal of Periodontology, 1987To determine the sensitivity and specificity of the radiographic detection of calculus, 275 proximal tooth surfaces from 18 patients were evaluated. Standardized periapical radiographs obtained before extraction were coded, batch processed, and evaluated independently by two investigators under optimum viewing conditions.

Aspirated dental calculus in a dog
Journal of the American Veterinary Medical Association, 1992Aspiration of a dental calculus, with lodgement of the calculus in a mainstem bronchus, was identified in a dog after dental prophylaxis. The calculus was located by use of radiography and bronchoscopy, and was removed via thoracotomy. Aspiration is a possible complication of dental prophylaxis.

Formation and Inhibition of Dental Calculus
Journal of Periodontology-Periodontics, 1969Indeed there has been an " i n f o r m a t i o n exp los ion" i n this f ield, as the author suggests, and it is grati fying to see the fragments being put i n their places.

A microbiological study of dental calculus.
Journal of Periodontal Research, 1978The flora of 16 supragingival and 11 subgingival calculus samples from 20 patients was studies using both selective media incubated aerobically and anaerobically. 767 representative isolates, from a total of 1,320 were charaterised and 653 assigned to genera or species.Gram‐positive organisms present in >50% of all samples were Streptococcus sanguis

Hyaluronic acid in supragingival dental calculus
Calcified Tissue Research, 1977A method is described for the isolation of heteropolysaccharides from human supragingival calculus. One component was identified as hyaluronic acid, by electrophoretic mobility, testicular hyaluronidase digestion and cetylpyridinium chloride profiles. No sulphated glycosaminoglycans were detected.
